I do not even monitor my water intake... Even when I was on diet hiatus I still drank over a gallon a day. (I know this because I fill a gallon jug up with well water) I have seen several posts on here saying that maybe they were drinking too much water.. I don't get it, what problems would that cause? Just curious... Thanks!

In the most extreme case, yes, there is such a thing as too much water. I remember there was news about someone who died from drinking a lot (really a lot!) of water and it flushed out the salt and minerals from her body or something like that but that's drinking a really insane amount of water though...there's a list of people who died from drinking too much water in the wiki page for water intoxication. Too much of anything is bad in general.

I think most of those worrying about drinking too much water here are just afraid of water weight causing a higher number on the scale.
